Abstract

With this start-up control apparatus it is intended to reduce the starting jerk at elevators resulting from superimposing the motor cut-on moment and load moment and to improve the starting comfort of the elevator passengers. The brake magnet of the electromechanical holding brake of the elevator is connected for this purpose with a regulation device, by means of which there can be linearly decreasingly controlled the braking force during the elevator's start-up, so that there can be obtained a linearly ascending start-up moment of the drive. The linear decrease of the braking force first appears following decay of the cut-on moment peak of the drive motor. This can be obtained by optimum correlation of the start-up time point of a reference value transmitter of the regulation device and the drive motor as well as the proportional part (P-part) of the reference value transmitter, whose transfer function approximately corresponds to the time behavior of a PI-regulator. The cut-on moment peak can only have an inappreciable effect, since the brake spring is dimensioned such that the mechanical brake moment amounts to 3-fold to 3.5-fold of the motor rated moment or torque.
